<h1>Types and the type system</h1>
<h2>Algebraic types</h2>
Blend is based on an algebraic type system. Algebraic types are composed out of other types using constructors. This is also possible with tuples.
<h2>List of basic types</h2>
Although additional types are scheduled to be implemented, I chose these basic types to implement and make available immediately since they seem to me to be the most important ones.
<h3>Integer types:</h3>
* Bignum:An integer type with nearly unlimited precision
* Int8, Int16, Int32, Int64, Int128: Signed integers with the indicated length
* UInt8, UInt16, UInt32, UInt64, UInt128: Unsigned integers with the indicated length
* Rational: A rational number of unlimited precision
* Float32, Float64: IEEE floating point numbers of different length
* Complex32, Complex64: Complex numbers consisting of two IEEE floating point numbers of the appropriate length
<h3>Special types:</h3>
* Boolean: has two literal values (True and False) which represent truth values
* Maybe: Has two constructors (Nothing an Just) which represent either nothing or a value.
* Either: Has two constructors, Left and Right. The Left constructor holds an error, the right one a result.
